FYI the :LTZ is the "sport suspension package" that was available on the Caprice. I have a 93 w/ the detuned L05. It does have the 3.08 rear end w/ the GU4 positraction, F/R sway bars and higher rate front springs( possibly proportional rate)7TN, non-variable power assist steering,Al wheels, thick leather wrapped s/wheel,certified speedo, gas bib(white),short hood ornament(BA1) and the RPO code shows MD8 to be the THM 700R4 trans(?). From the post I have seen the frame is supposed to be the same as the 9C1. I have yet to find the following RPO codes that are on the car( IQC, UU8, U41, 1AY, 1SZ).
